This transparent enamel is a soft fusing clear that will clear up on copper in the first firing; it may produce "break up" or "pull through" when a subsequent coat of enamel is fired high. Formulated to perform beautifully on a variety of metal and glass substrates, Thompson lead-free enamels are quality-made to deliver dependable, repeatable results. This medium-temperature, high acid-resistant enamel fires at temperatures from 1,400°–1,500°F (760°–815°C) on fine silver, copper, gold, low-carbon steel and fired fine-silver, copper or gold metal clay.
• The enamel on the sample shown on this page was applied over textured copper.
• Before firing, in this powder form, this 80-mesh enamel will not look as it will after firing.
• It is always prudent to pre-test enamel colors on examples of the workpieces you are using to resolve any slight variances that may occur in different batches of enamel and its performance on your specific metals.
